I RECUPERATOR-WALL.

Specification of Letterslatent.

3, 1916. Serial-No. 69,995.

To all whom it may concern Be it known that I, ARTHU ROBERTS, a

citizen of the UnitcdSt-ates, residing at- Evai'iston, county of Cook, and. State of Illinois, have invented certain new and useful.

Improvements in Recuperator-'Walls, of

- which the follovving is a specification.

This application is a division of my copending application for Letters Patent of I the United States .on improvements in recuperative coke-ovens, Serial No. 875,503,

filed; December 1, 1914.

In that application, there is disclosed a.

" coke oven construction, in which recuperator walls are placed between the adjacent heating walls of the adjacent coke ovens of a bench, and that application relates generally to constructions in which the said recuperator walls are independent of the heatingwalls to the extent that they may expand and contract independently of the heating walls, and to the extent that they maybe constructed or maintained as independent elements or portions of the bench ofcoke OVBIIS.

This present application relates to a gen-' eral type of recuperator wall construction,

tion be independent of the adjacent heating walls in the manner and to the extent of the construction disclosed. in the aforementioned application.

- corresponding, substantially simultaneous,

' provide a withdrawal of heat units from the other side of the'structure. The rate at which the heat may bedelivered intoor withdrawn from said structure depends, among other things,up0n the intimacy of' contact of all portions of the heat carrying medium, orthe heat extracting medium, with said struc-' ture.

One of the objects of this invention is to i 4 recuperating wall construction of such form that the air or gas will be driven with great frequencyand violence against portions ofthe structure so as to bring all combination with openings construction and combinations of regardless of whether or not such construcportionsof the said air or gas into direct and forclble contact with the structure one Patented Aug. 1, 1916.; Original application filed December 4, 1914, Serial No. 875,503. Divided and this application filed J nna-er or more times and at one or more points during the travel of the air or gas adjacent to sa d structure. That is to say, the" main ob ect of the invention is to so (onstruct the recuperating walls that the trans er of heat into the air or gas traveling through it will be occasioned largely by the impingement principle disclosed in my co pending appli I cation for Letters Patent of the United States on improvements in the art of heating, Serial X0. 43,753, filedAugust 5,1915.

Another object of the invention is to provide a recuperating wall construction of extremely simple form, so that it can be built from a minimum number of blockforms. Also to so construct the wall that it will be p ovided with a mesh of impingement passages contained within its body portion in or passages in its upper and lowerportions for the transfer of theair or gas to andfroin thesaid mesh.

Other objects and uses of the invention will appear from-a detailed description of the same, which consists in the features of inafterdescribed and claimed.

Referring to drawings: Figure 1 shows a vertical cross section through two adjacent coke ovens of a bench, and through the inter mediate recuperating wall; Fig. 2 showsa plan view of a simple form of block used. in building up the recuperating wall; Fig. 3 shows'a side elevation .of the block illus trated in Fig. 2; Fig. 4 is a horizontal sec tion through two heating walls and the in termediate recuperating wall of the par ticular construction shown in Fig. 1, Fig. 4 being taken on the line H of. Fig. 1, looking in the direction of the arrows; Fig. 5 is a horizontal section, taken on line 55 of Fig. 1, looking in the direction of the arparts hererows; and Fig. 6 is aventical sectiontlirough particular recuperating wall.

-tures of invention herein disclosed are adapted for use in many recuperator wall locations and in many particular recuperator wall constructions. Forconvenienceof illustration and description, however, I hare being taken on the line 6-6- shown said features as applied in a particu lar manner, said application being one in whlch the recuperator wall 1s placed between two adjacent oven heating walls.

However, said features might also be applied in recuperating Walls for usein many other locations than in the particular location above mentioned.

In the arrangement illustrated, the two adjacent carbonizing chambers are designated by the numerals 7 and 8, respectively. They have the adjacent heating walls 9 and 10. Each of said heating walls has on its interior, gas passages of suitable construc tion, and rows of nozzles 11 and 12 deliver the heating gases to the walls 9 and 10. In the particular arrangement illustrated, the fuel for said nozzles is delivered by a manifold 13. The heating gases travel down through the heating walls and collect in the sole passages 14: and 15, whence they may be withdrawn in any desired manner.

In the particular arrangement illustrated, I have shown the recuperating wall 16 between heating walls 9 and 10. Reference to Figs. 1, 45 and 5 shows the narrow spaces 17 and 18 between this recuperating wall and the adjacent heating walls. These spaces, however, are taken up by the sidewise expansion of variousparts as they approach working temperature so that, when the ovens are at working temperature, the heating walls contact firmly against the recuperating wall.

Reference to Fig. 6 shows a meshwork of horizontally and vertically extending passages 19. These passages extend throughout substantially the entire height and length of the recuperating wall, or, at any rate, throughout those portions of the recuperating wall in which the features of the present invention are applied. These horizontally and vertically extending passages are in communication with each other, but they are so formed that the air or gas in traveling through them, is forced to frequently and violently change its direction of travel.

Consequently, the heat will be transmitted directly between the. wall and the air or gas in such a manner that a maximum ethcienry of such heat transfer will be effected.

In the particular construction illustrated, the recuperating wall, with its mesh of passages, is built {up fronrblocks of peculiar construction. fThese blocks have their side and horizontal faces so recessed that, when they are laid together, they provide a meshwork of horizontally and vertically extending passages in the recuperating wall. By so setting the blocks as to cause them to break joints vertically. the ineshwork of passages will be zigzag in form, as shown in Fig. (3. One particular construction of such a block is that shown 1n Figs. 2 and 3. Examination of these figures shows that such a block as that illustrated has its side faces recessed at 20 and 21, and its bottom face recessed at 22. Examination of Figs. 4: and

5 shows that the end portions of the blocks taper alternately inward and outward, so that when the blocks are laid together, they keystone together in the manner shown in said figures.

The recuperator wall is so constructed that the air or. gas can be delivered to the entire lower edge of the mesh of passages, and is, furthermore, so constructed that the heated air or gas can be directly delivered to each and every burnerf For thispurpose, a channel 23 extends across the bench beneath each recuperating wall, said channel communicating directly with the mesh of impingement passages throughout its entire length. The air or gas may be delivered to the channel 23 inany desired,manner, and I do not concern myself in this application particularly with the manner of such delivery.

In the particular construction illustrated the recuperator wall effects the heating of the air which is to be supplied to the burners. Now referring to the upper portions of Figs. 1 and 6, it will be noted that each of the burners 11 and 12 receives its air supply from a side opening 2-1. These side openings communicate directly with the upper portion of the mesh of impingement passages, and, inasmuch as the burners are spaced throughout the length of the even, it follows that the heated air is withdrawn from the recuperating wall throughout p 'actically the entire length of the same.

It will be seen from an examination of the structure disclosed herein that the recuperator wall is provided on its interior portion with a network or mesh of interconnected passages extending in zig-zag fashion from one edge of the wall to another, so that the air or gas flowing between said edges is compelled to travel in a zig'zag manner from the one to the other. It will also be observed that as far as this particular feature of the construction is concerned, the recuperator wall may be placed adjacent to one or more of the heating walls of the oven, or may be placed at any other location desired in the particular construction to which it is applied.

I claim 1. A recuperator wall comprising a plurality of blocks laid up in courses, the blocksof each course breaking joints with the blocks 1 the wall and in communication with said.

meshwork ot' passages at that edge, and a plurality of burner connections adjacent to thenther edge of the wall and in communication with saidmeshwork of passages at 2, A recuperator-vvall comprising a plurality ofblocks laid up in courses, the blocks of eachv course breaking joints with the blocks of thev adjacent courses, and each block being recessed on one vertical face and one horizontal face to provide a meshwork of interconnected horizontally and-.ver'tically extending passages," a channel vextending cal face and one horizontal face recessed, and

the blocks being laid up in such a manner as meshwork.

to present a meshwork of "interconnected passages, a channel extendlng along one edge of the wall and in communication with said meshwork at that edge, and a plurality of burner connections adjacent to another edgeof the Wall and in communication with said meshwork'adjacent to said edge.

4;. A recuperator Wall comprising a "plurality of blocks, said blocks being recessed on two adjacent faces to provide a mesh- -work of interconnected passages on vthe interior of the Wall, a channel extending along one edge of the Wall and in communication with said meshwork, and a plurality of burner connections adjacent to another edge of the wall and in communication with said ARTHUR ROBERTS.
